Embodiments of the invention

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

1 is a flowchart of a method for implementing QoS management of a wireless network according to an embodiment of the present invention. As shown in FIG. 1, the method includes:

Step 100: Obtain QoS resource information that can be utilized by the wireless network, and a service type that the device transmits through the wireless network and QoS resource information that the device actually allocates; wherein:

In one aspect, collecting information on the radio base station and the core network, such as a GPRS service support node and/or a mobility management entity (SGSN/MME), determining the radio network bearer capability, and according to the collected radio network, the bandwidth allocated to the access device Analyze and extract the available QoS resource information of the wireless network surplus and idle.

On the other hand, through PCEF's deep packet inspection technology, the service type information transmitted by the device through the network is collected and obtained, and the service type includes one or more of the following types: VoIP, voice, interactive games, video and video conference, etc. The service type can also be understood as a media type; the service type information and the QoS resource information actually allocated by the device (such as the device) are collected through interaction with the Policy and Charging Rule Function (PCRF) network element. In fact, QoS indicators such as network bandwidth, QoS indicators and QoS resources described below).

Step 101: According to the QoS resource information that is actually allocated by the device, determine that the reference QoS or the actual scenario requirement corresponding to the service cannot be met, and evaluate the QoS resources available to the radio bearer network, and pass the authentication according to the QoS resources available to the wireless network. The QoS indicators of the device are adjusted.

In this step, if it is determined that the reference QoS or the actual scenario requirement corresponding to the service is met, the process ends.

In this step, the reference QoS or the actual scenario requirements that cannot meet the service according to the QoS resource information that is actually allocated by the device include:

Determining whether there is a QoS indicator for the wireless network of the device according to the QoS resource information actually allocated by the device, such as the QoS indicator such as the actual network bandwidth of the device, the service type of the device transmitted by the wireless network, and the reference QoS or actual scenario requirement of the service type. Necessary adjustment: When the actual allocated QoS resource information of the device is lower than the reference QoS or actual scenario requirement of the service type transmitted by the device through the wireless network, it is determined that the QoS indicator of the device needs to be adjusted, so as to provide more Excellent network communication service. It should be noted that the reference QoS of the service type transmitted by the device through the wireless network defines a basic QOS indicator that satisfies the multiple service types used by the device on the Internet, and can be referred to the related protocol. The allocated QoS resource refers to a resource that is occupied and cannot be used by other devices.

In this step, adjusting the QoS indicators of the authenticated device according to the QoS resources available to the wireless network includes:

Determining whether the QoS indicator required by the device can be provided according to the obtained QoS resource information of the wireless network, that is, the available QoS resources of the wireless network, and if necessary, the QoS indicator adjustment can be pushed to the device. The instruction is recommended to initiate adjustment of the QoS indicator, or to determine that the QoS indicator required by the device can be provided to automatically adjust the QoS indicator of the device. The QoS indicator adjustment instruction may be determined according to actual equipment and application conditions. For example, for a mobile phone user, the command is a configurable short message template. In this case, the short message is sent to the user's device, and the user is informed that the current network is unstable, cannot meet the current Internet access requirements, and needs to improve the network service quality. According to the needs of different operators in actual operation, the short message template may be different, and may inform the user to generate more traffic or extra charges.

The device receives the QoS indicator adjustment instruction and sends a QoS indicator adjustment instruction to the PCRF according to the Rx interface protocol to propose a QoS indicator adjustment request; in this example, the user response agrees to adjust the QoS indicator;

The PCRF sends a QoS indicator adjustment command to the PCEF, and the PCRF collects the adjustment result from the PCEF, and finally feeds back the QoS indicator adjustment result to the device, and completes the adjustment of the QoS indicator of the device. Here, when the QoS indicator adjustment instruction is actually used by the Rx interface, the corresponding parameters, such as the priority, the maximum uplink bandwidth, the maximum downlink bandwidth, and the like, are provided according to the actual situation of the adjustment of the target user, which is not limited herein.

When the selection automatically adjusts the QoS indicator of the device, the foregoing method further includes:

The QoS indicator adjustment command is automatically sent to the PCRF according to the Rx interface protocol, and the PCRF sends a QoS indicator adjustment command to the PCEF, and the PCRF collects the adjustment result from the PCEF, as needed (in some scenarios, the QoS resource adjustment does not need to notify the device, but Some scenarios need to be informed. The QoS indicator adjustment result is fed back to the device to complete the QoS indicator adjustment of the device.

The embodiment of the present invention analyzes the QoS index of the operator's wireless network, especially the idle amount of the network bandwidth, and analyzes the actual requirements of the QoS when the device accesses the wireless network, and discovers the wireless network. The QoS of the network is redundant and idle, and the device can make an instruction to adjust the QoS indicator to the device when the QoS indicator actually enjoyed by the device cannot meet the service type of the network transmission under normal conditions, and accept and respond to the adjustment command. The QoS indicator of the device is implemented, or the QoS indicator is automatically adjusted for the device. In this way, the operator's excess bandwidth is effectively and reasonably utilized to provide better network communication services for the device.

The processing module 204 determines whether to recommend adjusting the QoS indicator for the device or automatically adjusting the QoS indicator for the device according to the type or attribute information of the device. When the manner of recommending the QoS indicator is adjusted, the processing module 204 pushes the QoS indicator adjustment suggestion instruction to the device, and if the device response processing module 204 receives the adjustment suggestion instruction, adjusts the QoS indicator according to the recommendation (may be provided in the manner provided in the recommended instruction) In response, the processing module 204 sends a formal adjustment notification to the network interaction module 203, instructing the network interaction module to interact with the PCRF network element, and the notification message includes the QoS indicator to be adjusted; when the automatic adjustment of the QoS indicator is adopted The processing module automatically sends a formal adjustment notification to the network interaction module, indicating that the network interaction module interacts with the PCRF network element, and the notification message includes the QoS indicator to be adjusted.

QoS metrics or actual scenario requirements. At the same time, the QoS decision module 203 determines that the radio bearer capability of the current wireless network can meet the QoS specifications required by the device. In addition, when the authentication device has the condition for adjusting the QoS indicator, the QoS of the wireless network of the device is required. Indicators are adjusted;

Step 601: If the device feedback requests to improve the QoS, the QoS indicator adjustment request may be submitted to the processing module 204 by using a short message or an API interface manner;

Step 602: The processing module 204 sends a QoS indicator adjustment instruction to the network interaction module 202.

Step 603: The network interaction module 202 interacts with the PCRF network element through the Rx protocol interface, for example, sends an AAR request message to the PCRF, and requests the device to perform QoS index adjustment.

The AAR is a protocol interface message. According to the protocol, the method includes a plurality of parameters, and the operation type is included in the parameter. In this step, the QoS operation type is requested, and the corresponding QoS condition is queried in the step 400. The other parameters corresponding to these two types of processes are also different.

Step 604: The PCRF and the PCEF are exchanged through the Gx protocol interface, and the PCRF can use the RAR message to notify the PCEF to adjust the QoS index of the device.

Step 605: After the PCEF completes the adjustment, the QoS indicator adjustment result may be reported to the PCRF by using the RAA message.

Step 606: After receiving the QoS indicator adjustment result of the PCEF, the PCRF may use an AAA message to feed back the adjustment result of the QoS indicator for the device to the network interaction module 202.

Step 607: The network interaction module 202 returns a QoS indicator adjustment result to the processing module 204.

Step 611: The processing module 204 notifies the device to perform QoS adjustment for the QoS indicator adjustment result.

It should be noted that, in the case of automatically adjusting the QoS indicator for the device, the interaction with the device is not involved, and only steps 602 to 608 are required.
